The PCD5013 automatically prompts the host to read a
Roaming Status Packet if RSR, MS1, MFI, MS2, MBI,
MAW, NBU, NDR 1, NDR 0, or SCU is set.
RSR:
re-synchronization signal received (Table 19).
Set when the PCD5013 detected a re-synchronization
signal (Ar/Ar) and the host configured the PCD5013 to
ignore it via the IRS bit in the roaming control packet. This
bit is cleared when read.
MS1:
missed synchronization 1 (Table 19). Set when the
PCD5013 fails to detect the first synchronization pattern
(A/A) of a FLEX
frame and the PCD5013 was configured
to report missed frame information via the MFC bit in the
roaming control packet. This bit is cleared when read.
MFI:
missed frame information word (Table 19). Set when
the frame information word is received with an
uncorrectable number of errors and the PCD5013 was
configured to report missed frame information via the MFC
bit in the roaming control packet. This bit is cleared when
read.
MS2:
missed synchronization 2 (Table 19). Set when the
PCD5013 failed to detect the second synchronization
pattern (C/C) of a frame and PCD5013 was configured to
report missed frame information via the MFC bit in the
roaming control packet. This bit is cleared when read.
MBI:
missed block information word 1 (Table 19).
Set when at least one of the block information word ones
is received with an uncorrectable number of errors and
PCD5013 was configured to report missed frame
information via the MFC bit in the roaming control packet.
This bit is set no more than once per frame regardless of
the number of missed block information word 1’s in the
frame. This bit is cleared when read.
MAW:
missed address word (Table 19). Set when any
address words in the address field is received with an
uncorrectable number of errors and PCD5013 was
configured to report missed frame information via the MFC
bit in the roaming control packet. This bit is set no more
than once per frame regardless of the number of missed
address words in the frame. This bit is cleared when read.
NBU:
network bit update (Table 19). Set when the NBC bit
in the roaming control packet is set and a frame
information word is received with a correctable number of
errors. This bit is not set when the frame information word
is not received due to missing the first synchronization
pattern (A/A). This bit is cleared when read.
n:
network bit value (Table 19). When NBU is set, this is
the value of the n bit in the last received frame information
word.
NDR:
noise detect result (Tables 18 and 19). These bits
indicate the result of a noise detect. The results of noise
detects initiated by setting the SND bit in the roaming
control packet is always reported. The results of the
automatic noise detects performed in asynchronous mode
is only reported if the RND bit is set in the roaming control
packet. When continuous noise detects during block data
are enabled by setting the CND bit in the roaming control
packet, only the ‘No FLEX
signal detected’ result is
reported. These bits are cleared when read.
Table 18
Noise Detect Result (NDR bits)
SCU:
system collapse update (Table 19). Set when the
PCD5013 is configured for manual collapse mode by
setting the MCM bit in the roaming control packet and the
system collapse of a frame is received. This bit is set no
more than once per frame regardless of the number of
phases in the frame. This bit is not set in frames in which
no block information word 1’s is received properly. This bit
is cleared when read.
RSC:
received system collapse (Table 19). When SCU is
set, this value represents the system collapse value that
was received in the frame.
